RWD Celica, Swapping Supra drivetrain into Celica Options

[darksecret]

I know some might flame me for this but I was doing some research and the Supra is almost the same size as the Celica, wheelbase is only around 23mm apart and the width hopfully rotor to rotor (still need to get exact measurement) is only 98mm apart. the width wont be much of a problem due to the flare on the rear fenders and length can be overcome by a custom bellhousing that will be required. I got the idea from the Top Secret Supra. I know the Getrag will be a tight fit but it might be possible to do this without cutting the firewall. I'm know most of the parts I need and I know how RWD vehicles are set up so that is covered, I also have a live in welder (uncle) so fab work isn't an issue. Some might think this is highly impractical and they're right but it's a great concept that I will pursue. I'm going to hit up Supra forums and try to get more measurements for the drivetrain, etc. If anyone that can help with research it will be appreciated. Anything will help but I could use shifter placement, 3S-GTE width pully to output shaft and Getrag input shaft length. As I pursue this project I will post what I can and if it bombs at least there will be information for any other brave soul that wants to take this on.

Alright I got off work and went straight to my garage lifted my car and checked the most important underside measurements, if everyone with a 6th Gen takes a measuring tape and check these same areas you will come close to these results, these might be an inch off but thats because I did this with all the parts still in the car, when I do strip it down I will measure in mm to be more accurate.

Engine Bay:

Top to Bottom Front: 21"
Top to Bottom Rear: 29" (I checked on the passenger side about 8" from the centerline)
Width: 36" (This is from the smallest points I can find)
Depth: 34" (This is from the radiator, not support to the firewall)
Driveshaft Tunnel Height: 7" (If the shift cable shield is removed there is a smooth area where I believe to be the mount area for the center diff.)
Driveshaft Tunnel Width: 6"
Driveshaft Tunnel Length: 64" (This goes from the firewall to the rear end housing area, the transmission and the rear end will take some of this area)
Rear End Width: 58" (From the backs of each rotor)
Rear End Height: 12" (This is probably a couple of inches off due to the gas tank)


If any one is wondering how I got the height measurements I used a level and went from the lowest chassis point on the car. On my car the actual lowest point is the cat.

I know the 3S is a different motor the the 5S but I checked it and for the people thinking that the 3S wont fit the bay then they are wrong. I can turn a 5S and still have 5"-6" of clearance on either side at the shortest point. I didn't mention anywhere that I probably won't keep A/C. Around here it's not that important.
